Revisional bariatric procedures in the group of patients over 60 years of age: a multicenter cohort study (PROSS Study)

Introduction
The constantly increasing prevalence of obesity in the population and the lengthening of life expectancy affect the appearance of the problem of pathological obesity also in the elderly. At the same time, an increase in the number of bariatric procedures (also revisional) performed in elderly patients is observed.

Aim
To assess the indications for revisional bariatric procedures along with the safety and postoperative results in the group of patients over 60 years of age.

Material and methods
The study was conducted in 2019–2020 among patients undergoing revisional bariatric procedures in Polish bariatric centers. The data were obtained through a multicenter, observational retrospective study.

Results
Our data consist of 55 (8.1%) patients older than 60 years of age who underwent revisional bariatric procedures. Revisional procedures in the group of patients over 60 years of age had fewer postoperative complications (16.4% vs. 23.1%, p < 0.05). Remission of type II diabetes or arterial hypertension was achieved to a lesser extent in patients operated on over the age of 60 (13% and 15%, respectively) compared to patients operated on under the age of 60 (47% and 34%, respectively; p < 0.05).

Conclusions
Revisional bariatric procedures in the group of patients over 60 years of age do not cause an increased risk of postoperative complications or prolonged hospital stay. The possibility of achieving remission or improvement in the treatment of comorbidities in patients operated on over 60 years of age is relatively lower compared to a younger group.
